Advancing Near‐Real‐Time Flood Inundation Mapping in Australia

Water Resources Research, Volume 62, Issue 2, February 2026.
Abstract Floods are the second‐most deadly natural hazard in Australia, following heatwaves. Monitoring flood extent and depth in near real‐time (NRT) is crucial to minimize loss of life and socio‐economic impacts. This study leverages advanced computing, data management systems, and high‐quality data, including river gauge data APIs and Australian ...

ICESat‐2 Pointing Calibration and Geolocation Performance

Earth and Space Science, 2021
ICESat‐2 science requirements are dependent on the accurate real‐time pointing control (i.e., geolocation control) and postprocessed geolocation knowledge of the laser altimeter surface returns. Prelaunch pointing alignment errors and postlaunch pointing

Dynamic Boundaries of Antarctic Active Subglacial Lakes Reveal Underestimated Water Volume Change and Overestimated Lakebed Active Area

Geophysical Research Letters, Volume 53, Issue 2, 28 January 2026.
Abstract This study revisited 158 documented active subglacial lakes across Antarctica, applying a height‐change anomaly delineation algorithm to CryoSat‐2 and ICESat‐2 satellite altimetry data to assemble a 14.75‐year (2010.5–2025.25) time series of active subglacial lake dynamics.

Water Storage Changes of Lakes and Reservoirs Across Asia (2018–2023) and Their Effects in Flood Control

Geophysical Research Letters, Volume 53, Issue 1, 16 January 2026.
Abstract Monitoring lake and reservoir water levels is critical for water resource management and flood risk mitigation. We integrate Sentinel‐3A/B and ICESat‐2 altimetry to reconstruct monthly water levels (2018–2023) for 7,433 lakes and reservoirs (>5 km2) across Asia and estimate their storage variations.

Small and Medium‐Sized Inland Waterbodies: Water Volume Predictions and Flood Implications

Water Resources Research, Volume 62, Issue 1, January 2026.
Abstract Small (<10 ha) and medium (10–100 ha) inland waterbodies are crucial for water storage and flood regulation, necessitating an improved understanding of their water volume. Traditional water volume measurement methods, modeling techniques, and advanced altimetry missions struggle to capture the non‐linear volume changes in these waterbodies ...
